Inventor: WATANABE NORIHISA
IPC: C23C18/18
Filed: 1998-11-26
Abstract: PROBLEM TO BE SOLVED: To omit a polishing process before a texturing process by successively subjecting the surface of a glass substrate to degreasing treatment, etching treatment, treatment with warm pure water, treatment with a silane coupling agent, activator treatment and accelerator treatment, and then subjecting to electroless Ni-P plating and to heat treating.

Abstract: PURPOSE:To efficiently and stably produce uraniumdioxide fuel kernel having no cracks and the like on the surface and of uniform and good quality by bringing hydrogen inclusive gas flow into contact with uraniumtrioxide particles contained in a sample containing means in a furnace. CONSTITUTION:A hydrogen gas cylinder is opened, hydrogen inclusive gas is introduced in a furnace 2 to make inside the furnace 2 a hydrogen inclusive gas atmosphere and it is gradually heated to ca. 1500 to 1600 deg.C. When the inside of the furnace 2 is heated to ca. 500 deg.C, the uraniumtrioxide particles 8 causes reduction reaction with the hydrogen inclusive gas flowing above it. Thus, uraniumdioxide is produced and resulting water molecules are produced. The water molecules move with the flow of hydrogen inclusive gas and is exhausted out of the furnace 2 through a gas exhaust pipe 9. Therefore, it never happens that the water molecules stagnate near the uraniumtrioxide particles 8. As the results, the uraniumtrioxide particles 8 efficiently causes reduction reaction with the hydrogen inclusive gas flowing above it and become uraniumdioxide successively.

Abstract: PURPOSE:To decrease the pitch of moire fringes to a negligible extent by setting the angle formed by the direction where the stripes of a light control film extend and the direction where the raster of a raster display device extends so as to have a prescribed angle. CONSTITUTION:This information display device is used by disposing the raster display device in a bright part of outdoors, etc., and is used for a vehicle, such as automobile.
